Washable vs Disposable Air Filters
Washable filters cost more up front but last years and reduce waste, though most are low efficiency (MERV 1–4) and must be cleaned and fully dried to avoid mold. Disposable pleated filters offer higher efficiency (MERV 8–13) and convenience. Choose washable for low-efficiency equipment protection and sustainability; choose disposable for better air quality.

Caring for washable filters
Rinse a washable filter on schedule, let it dry completely before reinstalling, and follow the airflow arrow. A damp filter put back into the system can grow mold and harm indoor air — drying fully is essential.
Frequently Asked Questions
Are washable air filters worth it?
They can save money over time and cut waste, but most are low efficiency. If air quality matters, a disposable pleated MERV 13 outperforms a typical washable filter. Higher-efficiency washable options exist but require diligent cleaning.
How do I clean a washable filter?
Rinse with water (and mild soap if needed) in the direction opposite normal airflow, then let it dry fully before reinstalling. Never run the system with a wet filter.
